Specification of Reissued Letters Patent.

Reissued Nov. 13, 1906.

Oiiginallin. 714,620, dated November 18, 1902. Application for reissue filed May 25,1906. Serial No. 318.789.

To all whom it may concern);

Be it known that 1, Lane G. NILSON, zen of the United States, Hoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Electric interrupter, of which the fol owing is a full,clear, and exact description.

This invention relates particularly .to interrupters for sparking induction-coils. In induction-coils operated by pulsatory electric current through the primary circuit the inductive efiects in the secondary circuit are proportional to the rapidity of the changes in the primary circuit. The highest tension or the brightest spark in the secondary is shown not atv the closing but at the opening or breaking of the primary circuit the cleaner or quicker the break the better the results.

It is well known that in ordinary induca citition-coils-using platinum-tipped contacts in the vibrator even with proper condensers the contactoints will burn or corrode more or less. T 's burning or arcing not only destroys the points rapidl'y,'but gives poor re-- sults in thesecondary ofthe coil. It is also well known that if an electric connection is broken, producing a spark or an arc in the magnsticfield, the magnetism will have a tendency to diminish or blow out the spark. In-order to produce the best results in inducsame time improve the action and prolong the life of the moving parts, I have provided an interrupter in which the magnetism of the interrupter itself is utilized for blowing out the destructive I will describe an electric interrupter emthe appended claims. Reference 1s.to be had to the. accompanying drawings, formin a part of this specifisimi ar characters of-reference indicate corresponding figures.

Figure 1 is an elevation of an interrupter embodying my invention, showing the same coil; and Fig. 2 is an elevation showing the action in the-magnetic field.

Referring to the drawings, 1 designates a two-pole electromagnet connected at one end through a wire 2 with a battery 3, the other end of the electromagnet being connected through a wire 4 with a vibratory strip 5 of non-magnetic metal.

and 'a resident of parts in both the This strip 5 is sup-' ported acro'ssthe poles of the electromagnet,

and arranged on the upper side of the strip 6 7, having opposite poare the armatures larities and magnetically separated, each armature being oppos'te one pole of the magnet. Secured to the strip '5 between the inner ends of the armatures is aplatinum contact-point 8, designed to be engaged by a latinum point 9 on an adjusting-screw 10. it will be noted that the inner ends of the armatures are curved upward andthat both contact-points 8 and 9 are wholly embraced in the enlargedfield provided by so upwardly curving the ends. The point 9 through the .screw 10 and its support is connected by a wire 11 with theprimary 12 of the induc tion-coil, the said primary being also connected, by means of a wire 13, with the battery 3. h r

The secondary 14 of the induction-coil is connected in the usual manner with the sparking points.

A condenser 15' is in connection with the wire 11 and with one end of the strip 5. The circuit may be ,traced'from the battery through the wire -2, the electromagnet,

the wire 4, the vibratory str1p 5, the-contacts substantially the same as that in any other similar system of inductiomcoil; but my improvernent consists, essentially, in placing the contacts of the interrupter in a powerful magnetic field, the magnetic action is shown in dotted lines in Fig. 2.

Having thus described my invention, I de clare that what I claim as new, and desire to secure by Letters Patent, is
